Keras always predicts same class

Web2 okt. 2024 · However, when applied on real data (by taking one's ECG, computing the features and normalizing them by the same normalization value used on training and test set above), the network is always predicting: a label of 0.0 for "normal" ECGs; a label of 1.0 for noisy ECGs (which are taken as stressed ECGs). WebKeras model predicts correctly, but always at 100% confidence I'm trying to create my own model to classify a face as either wearing a mask or not, and by what ratio. This is my Colab notebook, with predictions output at the end. The question is: How do I make the model predict with confidence, for example: [0.966 0.034] ?

WebWhen I call predict () on the Keras model and look at the prediction results, then these are always either 0 or 1 (or at least very, very close to that, like 0.000001 and 0.999999). So my classifier seems to be quite sure whether an image belongs to either class "good" or "bad" (for example, if I am using only two classes).
